Description
BACKGROUND OF THE INVENTION
The present invention relates to a car location indicating and
burglarproof alarm device, and more particularly to a car-used
burglarproof alarm device which is designed as a main frame with a
simple pattern. The main frame is equipped with a clip member
enabling a user to easily mount the main frame on a sunshade or
instrument panel of the car by way of clipping. A user can operate
a portable controller to easily control the burglarproof alarm.
Therefore, the shortcomings of the conventional car-used
burglarproof alarm, that is, layout of complicated wires and
drilling operation are eliminated. An indicator is additionally
disposed on the car body, which can flicker under remote control of
the portable controller so as to help in finding the location of
the car.
A conventional car-used burglarproof device includes a control box
and a remote controller. The control box is installed on the car
body and a user via the remote controller activates or turns off
the burglarproof device. In the case that the car body is shook,
shocked or intruded, the burglarproof device according to the
signal of a sensor activates an alarm to emit alarm sound and
inform the user of the intrusion or shock.
In practical use, the above car-used burglarproof device has some
shortcomings as follows:
1. The complicated wires of the car-used burglarproof device must
be one by one mounted on the main circuit of the car by a
specialist. In addition, only by means of drilling or embedding of
the wires, the control box can be fixed in the car. Such
installation is time-consuming and inconvenient.
2. The respective wires of the car-used burglarproof device are
connected with the main circuit of the car body and the car-used
burglarproof device is powered by the battery of the car.
Therefore, under the condition that the burglarproof device is
activated while the car is not started, the load on the battery
will be increased and the discharging of the battery will be
speeded. As a result, it will be difficult or even impossible to
start the car and the battery will need to be replaced by a new
one.
On the other hand, the conventional car-used burglarproof device
often has an additional car-searching function. The car-used
burglarproof device is electrically connected with the head light,
light set or the horn of the car. Under a circumstance of poor
illumination or complicated environment, a user can use the remote
controller to control a receiver on the car body, which turns on
the head light, light set or horn to flicker or intermittently emit
sound for helping in locating the car. In order to achieve the
above function, the wires of the burglarproof device must be laid
in the car in a complicated manner. Moreover, in the case that the
car is parked among a number of cars and the head light of the car
is positioned at a relatively low position, the location of the car
will be difficult to find.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to
provide a car location indicating and burglarproof alarm device
including a main frame and a portable controller. The main frame is
equipped with a clip member enabling a user to easily mount the
main frame on a sunshade or instrument panel of the car by way of
clipping. Therefore, the shortcomings of the conventional car-used
burglarproof alarm, that is, layout of complicated wires and
drilling operation are eliminated. The portable controller is used
to remotely control and activate or turn off the burglarproof alarm
of the main frame. When a user via the portable controller gives
the main frame a command of activation, a built in shock sensor of
the main frame will sense the abnormal situations of the car body.
In the case of shaking, collision or intrusion, the shock sensor
will immediately send the abnormal information to a central
processing/controlling unit which will activate an indicator to
emit strong light or activate the alarm unit to emit alarming
sound. By means of the light and alarming sound, the user can be
clearly indicated of the situation and location of the car.
It is a further object of the present invention to provide the
above car location indicating and burglarproof alarm device in
which the main frame is installed at a higher position in the car.
Via a key pad of the portable controller, a user can directly
remotely control the main frame to activate the indicator to
intermittently emit strong light or activate the alarm unit to emit
alarming sound so as to effectively help a user in finding the
location of the car in a complicated or dim environment.
The present invention can be best understood through the following
description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Please refer to FIGS. 1 to 4. The present invention is composed of
a main frame 1 and a portable controller 2. The main frame 1
includes a central processing/controlling unit 11, a signal
receiving unit 12, a shock sensor 13, an indicator 14 and an alarm
unit 15. The main frame 1 is equipped with a clip member 18
enabling a user to easily mount the main frame 1 on a sunshade or
instrument panel of the car by way of clipping. The portable
controller 2 includes a microprocessing unit 21, signal
transmitting unit 22 and a key pad unit 23. The portable controller
2 is used to activate or turn off the burglarproof alarm of the
main frame 1. When a user via the key pad unit 23 of the portable
controller 2 gives the main frame 1 a command of activation or
turning off, the microprocessor 21 of the portable controller 2
further processes the signal transmitted by the key pad unit 23 and
determines the code previously set for activating or turning off
the burglarproof alarm. The code is further transformed by the
signal transmitting unit 22 and transmitted to the main frame 1.
The signal transmitting unit 22 is composed of an audiofrequency
controller 221 and a radio transmission unit 222. After the
microprocessor 21 sends the code to the audiofrequency controller
221, through frequency oscillation thereof, the code is transmitted
by the radio transmission
unit 222 to be received by the main frame 1. After the signal
receiving unit 12 of the main frame 1 receives the signal
transmitted from the portable controller 2, the signal is sent to
the central processing/controlling unit 11 for processing. In the
case of activation command, the central processing/controlling unit
11 will activate the shock sensor 13 which serves to sense the
abnormal situations of the car body, such as shaking, collision or
intrusion. The shock sensor 13 also is able to immediately send the
abnormal information to the central processing/controlling unit 11.
After receiving the information, the central processing/controlling
unit 11 will activate the indicator 14 to emit strong light or
activate the alarm unit 15 to emit sound or even through an
externally connected horn 16 on outer side of the car, the alarm
unit 15 can emit more apparent alarming sound. By means of the
alarming sound or flickering light, those persons around the car
can be informed of the abnormal situations and the location of the
car. The externally connected horn 16 is mounted at an external
position of the car by way of laying the wire so as to enhance the
volume of the alarm sound. In addition, the indicator 14 of the
present invention includes high illumination bulbs mounted in a
transparent cover 141 of the main frame 1. Via the key pad unit 23
of the portable controller 2, the indicator 14 can be activated by
the main frame 1 in the car to emit strong light or the alarm unit
15 can be activated to emit alarming sound so as to indicate the
user of location of the car. This is very helpful in searching the
car in a complicated or dim environment. Moreover, the main frame 1
is powered by a power source 17 for activating and maintaining the
functions thereof. The power source 17 includes several batteries
171 and a stabilizing circuit 172 for rectifying and supplying
power for the main frame 1. The portable controller 2 is also
powered by a power source 24 for maintaining the functions thereof.
The power source 24 includes several batteries 241 and a
stabilizing circuit 242 for rectifying and supplying power for the
portable controller 2.
According to the above arrangement, the car location indicating and
burglarproof alarm device of the present invention can achieve
double effects in a simple pattern. Therefore, the shortcomings of
the conventional car-used burglarproof alarm and location
indicating device, that is, complicated wires must be embedded in
the car and a drilling operation is necessitated are
eliminated.
The above embodiment is only used to illustrate the present
invention, not intended to limit the scope thereof. Many
modifications of the above embodiment can be made without departing
from the spirit of the present invention.
